Sewing a hooded sweatshirt is not as difficult as you may think. You don't necessarily need sewing patterns or pattern knowledge to make a sweatshirt. One simple method for a beginner sweatshirt project is to make it from an existing T-shirt in your size. To sew your own hooded sweatshirt, follow these instructions.
Things You'll Need
- Sweatshirt fabric and matching thread
- Fabric pencil
- Sewing equipment and supplies
- Ribbed sweatshirt fabric
- Iron and ironing board
Find an existing T-shirt in the size you would like your sweatshirt to be. You will not be destroying this shirt, so it can be as old or new as you like. Make sure the T-shirt is not made of stretchy material, as this will throw off the sizing.
Fold your length of sweatshirt fabric in half, creating a double layer. Lay your T-shirt on top of the sweatshirt fabric, with the sleeves folded back. Using your fabric pencil, add 1/2 inch to the sides, shoulders and collar. Add 1 inch to the bottom. Following your lines, cut out 2 pieces to use as the front and back.
Find the folded edge of the sweatshirt fabric, and line the sleeve of the T-shirt alongside it, with the top edge of the sleeve on the folded edge. With the fabric pencil, extend the bottom line of the sleeve as long as your arm, then draw upward to the fold. Extend the bottom line 1/2 inch lower, and add 1/2 inch to the side of the sleeve that connects to the shirt. Cut along your drawn lines, but do not cut through the fold. Open this sleeve piece and put it over a single layer of sweatshirt fabric, then cut a second sleeve piece.
Measure the length of the wrist side of the sleeve and the length of the bottom of the shirt front. In the ribbed fabric, cut two 6-inch-wide rectangles the length of the wrist measurement. Cut one 6-inch-wide rectangle 2 times the length of the shirt front measurement. Fold all pieces in half lengthwise, then iron them flat. Pin the nonfolded edge of each wrist-length ribbed fabric piece to the wrist side of each sleeve, right sides together. Stitch 1/2 inch away from the edge.
Pin the front and back pieces together at the shoulders, right sides together. Stitch 1/2 inch away from the edges and iron the seams flat. Open up the body and pin the sleeves to the armholes, matching up the middle of the curved sides of the sleeves to the shoulder seamlines. Stitch 1/2 inch away from the edges and iron the seams. Fold the body piece, right sides together, and pin the long sides together. Stitch 1/2 inch away from the edges, and iron them. Pin the nonfolded edge of the long ribbed rectangle to the bottom of the body, right sides together. Stitch 1/2 inch away from the edge and iron the seam.
Measure the distance around the neckline with a measuring tape. On a double layer of sweatshirt fabric, draw a straight horizontal line in that distance plus 1/2 inch. Put your sweatshirt on and measure the distance from the front of the neckline to the top of your head, plus an inch or two for ease. On one end of your drawn line, draw straight upward in this measurement. Also measure the distance from the front of the top of your head to the back, and add an inch or two for ease. Draw a curved line from the top of your vertical line to the free end of your horizontal line, making sure the top of the curved line equals this measurement. Add 1/2 inch to the side of this line and the horizontal line, and add 1 inch to the vertical line.
Cut along your lines so you have two hood pieces. Pin together the curved back line and stitch 1/2 inch away from the edge. Iron the seam. Fold back 1/2 inch of the vertical line and iron it flat, then fold back another 1/2 inch and stitch in place. Pin the horizontal line to the neckline of the sweatshirt, right sides together, making sure to match up the curved back seam with the middle of the sweatshirt back and the front sides with the middle of the sweatshirt front. Stitch 1/2 inch away from the edge and iron the seam.
